Answer:
it is b and e
Explanation:
<h2>if u look at the words twice you will notice that b and e are both saying the same meanings just in diff rent words way u need to look close on things like that and u will get passing grades </h2>
They go to special ed classes once theyre born
If acceleration is constant we calculate it from the formula:
a=
v=36
t=5s
We convert units:
t=5s=
h
a=
=432
=0,033333333333333
Answer:
Joining a club and getting a hobby
Explanation:
Join a club if you want to meet people, and when they choose a hobby it should be more than just gardening, because gardening sucks in the long term and it doesn't fill that gap. I know because my grandma did it and she is still sad.
Answer:
The magnitude of the stone velocity before it hits the ground is 30 m/s.
Explanation:
Given;
initial vertical velocity,
final vertical velocity, = 30 m/s
Apply the following kinematic equation to determine the height of the cliff;
Determine time of the journey;
h = vₓ + ¹/₂gt²
vₓ = 0 (initial horizontal velocity when the stone was thrown vertically downward)
h = ¹/₂gt²
t = √ (2h / g)
t = √ (2(40.82) / 9.8)
t = 2.89 s
When the rock is projected horizontally, the horizontal distance, x = 40.82 m
Initial horizontal velocity,
The final vertical component of the velocity is given by;
The magnitude of the stone velocity before it hits the ground is given by;
Therefore, the magnitude of the stone velocity before it hits the ground is 30 m/s.
